The full critical dynamics of the field \(h(x,t)\)  is evaluated at \(\tilde{D}=\tilde{D}_c\) . In Ref. [1]} it is shown that \(\tilde{D}_c\simeq 0.9\)  corresponds to the critical temperature \(T=T_c\)  of the 2D Ising model not only with periodic boundary conditions [2]} but also with the magnet boundary conditions shown in Fig. REF .
